Well I've got some rare mounts myself but I can't show screenshots since I've never bothered taking screenshots.
Here is my short list of rare mounts which probably pales in comparison to you guys ^_^
Azure Drake (first time ever drop! I didn't even know it was a mount drop!)
Ashes of Al'ar
Blue Proto Drake
Drake of the South Wind (Yeah the Al'akir one!)
Thundering Onyx Cloud Serpent (Not sure if it counts but I've won it 3 times)
and the White Hawk strider!
That's all my rares

I've been trying to level my warlock for well over a year now and I've only just hit level 60. There's something very difficult about their playstyle right from the get go. Surely it can't just be me? Is there any chance that the devs can streamline the class. Their resource system is also difficult to maintain as well.
